T o all whom 'it may concern: ,p

Be it known that l, CHARLES L. BETTS, a citizen of the United States, residing at New York, borough of IBrooklyn, in the county of Kings and State of New York, have invented a new and useful lm arovenient in Tubular Lanterns, of which the followingis aspeciiication, this application being a subdivision 22, 1906, Serial No. 344,585.

This invention relates' to that class of tubular lanterns which are provided-with a guard frame of basket form to which the lantern top is hinged for introducing and re-v moving the globe and which are provided with a removable oil pot, as in ordinary railroad lanterns.

The object of this invention is to provide the lantern with an open or skeleton bottom which is strong and rigid and also attractive in appearance.

ln the accompanying drawings: Figure 1 is a -side elevation of a tubular lantern provided with my improvements. Fig. 2 is a partly sectional elevation at right anglesto F ig. 1. Fig. 3 is a fragmentary vertical section, on an enlargedscale, of the upper portion of one of the tubes and connecting parts. Fig. 4 is a vertical transverse section in line lf-4, Fig. Fig. 5 is a sectionalperspectubes and connecting par-ts.

Like reference characters refer parts in the several figures. Y

A represents the oil pot and B the body hoop or lower ring of the lantern frame into which the oil pot is inserted from below and to which the oil pot is detachably secured by a spring fastening or bayonet catch of such construction that the oil pot is given a partial rotation in the body hoop B for engaging the oil pot with the spring fastening or disengag ing it therefrom. The spring fastening shown in the drawings is of well known construction and comprises a spring catch 10 on the body hoop and a stud l1 on the oil pot.

C represents the air tubes which are secured at their lower ends to the body hoop B and open through the same into the chamber 12 within the body hoop from which the burner 13 is supplied with air. These tubes extend upwardly to about the level of the upper guard ring-14. D represents the lan-V to like tern top ,which is connected with this guard ring by a hinge 15 at the rear side and a spring catch 16 at the front side of the lantern ina well known manner, so that the globe E canbe introduced into the guard from above. p l

F represents the metallic chimney which is arranged within the top D and bears upon the globe so as to hold the latter on its seatin the body hoop.

The hinged top D comprises a cylindrical wall 1.7 forming the outer wall of the upper air chamber, a horizontal base flange or plate 18, and elbows 19 which extend from the cylindrical wall outwardly and downwardly through the flange 18 and register with the vopen upper ends of the tubes when the top is closed down upon the guard.

20 represents the bottom guard ring and 21 represents the upright main guard wires or memberswhich are arranged between the tubes and extend from the top ring 14 to the bottom ring 2() and are secured at the waist of the lantern with their inturned portions to the body hoop.

22, Figs. 1, 2 and 5, represents short supplemental upright guard members or wires which extend from the lower portions of the air tubes down to the bottom ring 20 and are provided at their Lipper ends with hooks or bent ends which are inserted into the tubes through openings in the under side of the latter and rigidly secured therein by the tinning operation which is employed for finishing the frame.

The rigid lantern frame comprises the body hoop B, the air tubes O, the to` guard ring 14, the bottom guard ring 20, t ie main upright guard members 2l and the auxiliary guard members 22, and also preferably an intermediate guard ring 23 which is secured to the main guard members 21 and the air tubes.

I claim as my invention:

1.111 a tubular lantern, the combination of a body hoop, upright air tubes secured lwith their lower ends to the same, upright main guard members secured to the body hoop between the air tubes and extending upwardly and downwardly from the body hoop, supplemental upright guard members extending downwardly from the lower portions of the tubes, and a horizontal bottom ring connecting the lower ends of said upright guard members, substantially as set forth.

2. In a tubular lantern, the combination of a body hoop, upright air tubes secured with their lower ends to the same, upright main guard members secured to the body hoop between the air tubes and extending upwardly and downwardly from the hoop, supplemental upright guard members eX- tending downwardly from the lower portions of the tubes, a horizontal bottom ring connecting the lower ends of said upright guard members, and a horizontal top ring connecting the upper ends of the main upright guard members and the air tubes, substantially as set forth.

3. In a tubular lantern, the combination of a body hoop, upright airtubes secured with their lower ends to the same and provided in their lower portions with openings, upright main guard members secured to the body hoop between the air tubes and extending upwardly and downwardly from the body hoop, supplemental guard members extending downwardly from the lower portions of the tubes and having hooked upper ends which are engaged in said openings formed in the tubes, and a horizontal bottom ring connectingthe lower ends of said y upright guard members, substantially as set forth.
